Description

Suction device for gastrointestinal hemorrhage

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to an attraction device for gastrointestinal hemorrhage.

Background

Gastroscopy is a medical examination which is inserted into the stomach by means of a slender, flexible tube, and the doctor can directly observe lesions of the esophagus, stomach and duodenum, especially for small lesions. The gastroscopy can directly observe the real condition of the checked part, and can further definitely diagnose the pathological biopsy and cytology check of the suspicious lesion part, thereby being the first checking method of the upper digestive tract lesion. The upper gastrointestinal hemorrhage is a common disease clinically in medicine, and comprises bleeding at the anastomotic stoma and bleeding at stress ulcer after upper gastrointestinal operation and pancreas-duodenum operation, which are both acute in disease and serious in illness, and the upper gastrointestinal hemorrhage is a death risk if not treated in time. The patients with upper gastrointestinal hemorrhage often have more bloodshot and blood clots, so that the patients are difficult to peep and lesion and bleeding parts during gastroscopy, the aperture of a common gastroscopy channel is limited, and the common gastroscopy channel is difficult to rapidly and effectively attract, especially blood clots, the visual field is blocked quickly as soon as the gastroscopy is absorbed, the channel is blocked easily, and the gastroscopy channel is repeatedly taken out for cleaning the inner channel for a plurality of times, so that more pains are brought to the patients, and the treatment time is delayed. And when the bleeding amount of the patient is large, the accumulated blood in the stomach is difficult to clean up quickly, so that the bleeding position and the bleeding cause are more difficult to confirm. On the other hand, because the structure of the front section of the gastroscope is precise, the front section of the gastroscope is difficult to clean after being stained with blood, and the observation is also affected. This series of problems adds greater difficulty to the health care provider during the course of treatment.

Prior art, like patent CN111839425a discloses a gastroscopy auxiliary suction device, including the suction tube, the front end of suction tube has the traction head, and the suction tube front end has the suction hole that the side direction set up, and the suction tube rear end is connected with suction device, gastroscopy pipe front end is provided with the mobile mechanism who stirs the traction head, and mobile mechanism is controlled through the traction cable of wearing to establish on the gastroscopy pipe. The auxiliary suction device for gastroscopy can enter the gastric cavity through the alimentary canal inlet different from the gastroscope, and adopts the moving mechanism to move the end head of the suction tube to the position needing suction, which is often the region where semi-fluid objects such as blood clots, food residues and the like are concentrated, and the auxiliary suction device for gastroscopy does not enter the gastric cavity from the same channel with the inlet of the gastroscope tube, so that the suction tube with larger caliber is conditionally adopted, large semi-fluid objects can be efficiently sucked, and when the suction device is started, the semi-fluid objects can be easily sucked and discharged, so that clear and clean space is reserved for gastroscopy observation. Although this patent provides good aspiration of the contents of the gastric cavity, the patient is also required to suffer more pain during the treatment because the aspiration tube and gastroscope tube enter the gastric cavity from different entrances, which can easily cause discomfort to the patient and are more demanding to operate.

In addition, patent CN112168120a discloses a gastroscope external suction tube, which comprises a suction port and a suction port arranged at two ends, and a through port arranged in the middle and close to the suction port, wherein the suction tube further comprises a first connecting part which is connected with the suction port in a dislocation manner, and a first connecting part which is connected with the head end of the endoscope; the second connecting part is fixedly connected with the suction tube and is also connected with the endoscope body of the endoscope. The suction tube can enter the gastric cavity along with the gastroscope, so that the suction of accumulated blood can be performed, the condition of the gastric cavity can be observed, but suction is difficult to be completed when the accumulated blood clots are encountered, and the suction tube is blocked.

Therefore, how to design a device for sucking the blood stasis in the stomach and intestine, which has simple structure and convenient operation, can enter the stomach and intestine simultaneously to suck the blood stasis, and can not influence the stomach and intestine to observe the condition in the stomach and intestine due to the blockage of the blood stasis, is needed to be solved.
